Science in Focus: Energy: Workshop 6. Energy and Systems
Physicists use the concept of a system to trace and quantify the flow of energy. In this session, take a close look at a number of energy systems and see how this concept is closely linked to the Law of Conservation of Energy.,This segment explores the question "What is a system? by visiting classrooms as well as interviewing students and scientists.
Texas Tech Students Camp Out at Raiderville
More than 1,500 Texas Tech students want to be the first ones in Jones AT&T Stadium for Texas Tech's Sept. 18 showdown with the Texas Longhorns. Hundreds of tents comprise Raiderville, located by the old Southwest Conference bonfire pit near the stadium. Over the course of the week leading up to the game, random check-ins are conducted at Raiderville with students swiping their ID cards into the system. Each check-in gives the students more points. The students with the most points at

Glass transition: energy dissipation as rubber ball bounces at −50 °C
Part of a series of videos showing the glass transition in polymers, and the resulting change in energy dissipation on impact: Video at one tenth actual speed of a rubber ball bouncing at -50° C (just above Tg), showing that more of the elastic strain energy is dissipated, and the ball does not bounce as high.

14. Demographic Transition in Developing Countries
Global Problems of Population Growth (MCDB 150) By 1950, in most of the underdeveloped world, mortality had fallen to about half its pre-modern rate. The birth rate, however, had remained high and, by 1950, was about twice the death rate. For the rest of the century, both rates fell dramatically and in parallel, maintaining the gap. The enormous excess of births over deaths in this period is known as 'the population explosion.' By 1990, the world population was growing at almost 90 million a ye
16. Population in Traditional China
Global Problems of Population Growth (MCDB 150) China's early demographic history is similar to that of Europe; population grows only slowly due to war, disease and Malthusian resource limitation. Later, introduction of American foods allowed cultivated land to expand, but population expanded even more rapidly, leading to an extremely dense, but poor population. During this time, female infanticide was frequent, but almost all surviving girls got married. Within marriage, their fertility rate w
9. Demographic Transition in Europe
Global Problems of Population Growth (MCDB 150) Prior to the Demographic Transition, fertility in northwestern Europe was controlled by limiting marriage. Marriage was regulated by landowners and the churches, and was not allowed unless a man had accumulated the resources necessary to support a family. Long periods of being landless, a servant, or an apprentice, precluded marriage. Once married, there was no control of fertility. But, only about half of adults were married at any given time, so
Go with the Flow
Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. In a hands-on activity, students build a conductivity tester to determine whether different objects are conductors or insulators. In another activity, students use their understanding of electrical properties to choose appropriate materials to design and build their own basic circuit switch.
24.901 Language and its Structure I: Phonology (MIT)
24.901 is designed to give you a preliminary understanding of how the sound systems of different languages are structured, how and why they may differ from each other. The course also aims to provide you with analytical tools in phonology, enough to allow you to sketch the analysis of an entire phonological system by the end of the term. On a non-linguistic level, the couse aims to teach you by example the virtues of formulating precise and explicit descriptive statements; and to develop your sk

ESD.36J System and Project Management (MIT)
The course is designed for students in the System Design and Management (SDM) program and therefore assumes that you already have a basic knowledge of project management. The objective is to introduce advanced methods and tools of project management in a realistic context such that they can be taken back to the workplace to improve management of development projects. In contrast to traditional courses on the subject we will emphasize scenarios that cannot be fully predicted such as task iteratio
